Specification of Letters Patent. j

Application filed April 22, 1916. Serial No. 92,992.

Tov all whom t may concern:

Be itknown that I, THOMAS lSrAcrE, a citizen of the United States, and aresident ofl Bluelsland, in the county of Cook and State oflllinois,have invented 'a new and Improved Roller-Skate, of which the fol* lowingis a full, clear, and exact description.

This invention relates to games and toys and has particular reference toskates made chiey of sheet metal.

Amongthe objects of the invention is to improve this class of deviceswhereby they may be cheapened in construction without materiallya'ecting their reliability.

1 With the foregoing and other objects in view, the invention consistsin the arrangementfand `combination of parts hereinafter described andclaimed, and while the invention is not restricted to the exact detailsof construction disclosed herein, still lfor the purpose of illustratinga practicalembodiment thereof reference is had to the accompanyingdrawings, in which like reference characters designate the same parts inthe several views, and in which- Figure 1 is a vertical longitudinalsection on the line 1-1 of Fig. 2; Fig. 2 is a front elevation; and Fig.3 is a perspective detail view of the anchor device.

Referring now more particularly to the drawings wherein is shown thefront portion only of my improved skate, I provide a sole plate 10slightly curved at its front end to correspond to the usual form of theshoe or boot sole, but having downwardly projecting strengthening sideflanges 11.- The flanges are comparatively narrow or shallow for economyof material, but provide ample strength or stiffness for the sole platewhere the maximum strain occurs. The sole plate is provided with a pairof guide studs 12 along which a pair of claws 13 are guided for movementtoward and from each other transversely of the sole plate by means of aright and left screw 14 of well known form, the screw acting throughdownwardly projecting lugs 13 of the claws.

The rollers 15 are journaled in any suitable manner upon an axle 16extending transversely through a cradle member 17 including a tubularsleeve 18 having direct engagement with the axle. The body of the cradlereceives a cushion 19 of some suitable resilient material, the samebeing held between front and rear parallel lugs 20 having alined holesthrough which a pivot pin 21 projects, thereby locking the cushion inplace also. The pin at its middle portion is provided with projections21 which limitI the downward or rearward movement of the pin withrespect to the cradle.` The upper end of the pin constitutes a head 22having a spherical concavity in the extreme end pro` jectlng into agroove 23 formed around the centralportion of the screw 14. This pin,therefore, serves not only as a connecting pivot pin for the cradle, butalso as abrace for the clamping claws through the screw. As noted inFig. l, the head 22 projects well around one half of the screw.

-At 24 is indicated a cap iitted over. the upper surface of the cushion19. This cap is provided with a pair of slots 25 adjacent its upper andlower ends.

The main support between the sole plate and the cradle consists of apair of pedestal members 26 and 27. The member 26 is riveted orotherwise rigidly secured at its .upper end at 2S to the bottom of thesole plate Vand has an ear 29 projecting down wardly through the upperslot 25 of the cap plate 24 just in front of the cradle lug 20. The pin2l projects through a hole in this lug 29 and the projections 21 beardirectly against the front face thereof. The member 26 is thus locked tothe cradle, but a limited amount of lateral rocking movement around thepin 21 is permitted.

The other pedestal plate 27 is a channel structure and is riveted orotherwise secured at 30 to the sole plate at its upper end. The lowerend of this plate constitutes a lug 31 extending downwardly through theother slot 25 and having the lower end of the pin 21 extendingtherethrough as clearly shown in Fig. 1. This pedestal structure is verycheap in its make-up, being stamped and formed from sheet metal, but isof maximum rigidity.

The heel portion of the skate is not shown, but a rib 32 that connectsthe sole and heel portions is indicated, and the means for securing thefront end of the rib and constituting a part of the novel features ofthis invention are illustrated. The main securing means for the rib isan anchor piece 33 shown in detail inV Fig. 3, the same being stampedfrom sheet metal and having a web 34 lying against the bottom surface ofthe rib and provided adjacent its front end with a transverse slot 35.At the rear end the anchor plate is cupped or depressed at 36 PatentedDec. 12, 1916- llO to receive a nut 37 through which a set screwA 38projects andbears against the bottom of the rib to determine therelative lengthwise adjustment of the rib and sole plate. The web of thepedestal member 37 has an upwardly projecting central lug 39 which fitsinto the anchor slot 35. The side webs or flanges 40 of the anchormember extend upwardly and thence laterally forming wings 41 throughwhich the rear portion vof the anchor -is clamped rigidly at 42 to therear end of the sole plate. These side flanges 40 and ears Yform a rigidstable guide for the rib, preventing all tendency to lateral twisting orvibration without the vnecessity for any downwardly projecting parts orflanges at the extreme rear edge or end of the sole'plate, an importantelement of simplicity and economy in construction.

I claim:

1. 'In a Vroller skate, the combination with a soleplate, a pair ofclamping claws slidable towardand from Aeach other along said plate, anda right and left screw coperating w-ithfsaid claws to control theiroperation, said screw having a circumferential groove at its centralportion, of a pedestal secured to the bottom of the sole plate, a pairof wheels, fa cradle connected tothe wheels and cooperatingV with thelower end of the ped estal, and a pivot pin extending through thepedestalr and cradle electing the pivotal connection, said pivot pinhaving means projecting laterallyV therefrom to limit the eX- tent ofprojection through the pedestal and cradle andhaving an arc-shaped headat its upper end extending into said groove and serving-'to brace saidscrew.

2. In a roller skate, the combination of a sole plate having a flatflangeless rear end, Va longitudinal rib adjustably connected 4to thesole plate and extending rearwardly therefrom, and an anchor member Vfordeterminiing the adjustment Vof the rib, said Vanchor me l, ber beingVformed of sheet metal and comprising a horizontal web and upwardlyprojecting side ytlanges embracing' the sides of the rib and preventinglateral Ymovement of the rib and a pair of wings extending laterallyfrom the upper vedges ofthe .flanges for positive rigid connection tothev sole plate, and a clamping screw carried by the anchor member l andbearing Vupwardly against the bottom of -the rib, substantially as setforth. j
